Not long ago, taking a shower involved just turning the knobs on a couple of plumbing fixtures and waiting for the water to heat up. Now Kohler takes that simple task to the next level with DTV (Digital Thermostatic Valve), a waterproof control panel that lets you dial up the exact temperature of your shower.

The DTV also links up to Kohler's sophisticated multihead shower systems, its touchscreen allowing you to individually control pressure and temperature on up to eight shower heads. Better save up your money, though, because the controller alone costs $2000, not including a rather involved installation of all those shower heads and plumbing hardware. And then you'll have to pay for all those millions of gallons of hot water.
